ADJUSTABLE HAME-DRAFT.

Specification of Letters Patent.

Patented Jan. 25, 1916.

To all whom it may concern:

Be it known that I, JAMES M. HUDSON, a citizen of the United States,residing at Blanchester, in the county of Clinton and State of Ohio,have invented new and useful Improvements. in Adjustable Hame- Drafts,of which the following is a specification.

My invention relates to adjustable drafthames, its object being toproduce a cheap, strong and durable connection for the tug link, wherebythe same may be readily adjusted to different draft positions on thehame.

To this end, it consists in a hame connection embodying a bar or staplefor the engagement of the tug link, projected downwardly at each end topass through and engage the device with the hame; and, united therewith,an intervening trough-shaped structure formed by corresponding ribsdiverging outwardly and downwardly at both sides and merging in arectangular annulus constituting the base edge of an elongated invertedtrough-shaped structure which rests in contact with the hame. There isthus formed a truss support at each side of the staple, one incompression and one in elongation, which add greatly to the resistingstrength of the bar and permanency of the structure. The tug link ispreferably U-shaped, with the terminals bent to hookform to pass betweenthe side ribs and engage over the bar or staple.

It consists further in the combination with the hollow structure thusdescribed of an elongated strip of resilient metal curved or bentlongitudinally along its center line to a V-shaped or curved crosssection, placed within the trough-shaped structure, and retained thereinwithout fastening, and bearing upwardly against the hooks of the tuglink when engaged on the bar or staple, and preventing displacementuntil sufficient force is applied to turn the link over to be taken outand replaced elsewhere.

My invention is illustrated in the accompanying drawings, in which-Figure 1 is a perspective view of my improved fastening complete showingthe parts detached; Fig. 2 is a side elevation of the device complete inposition; Figs. 3 and 4L are opposite end views; and Fig. 5 is crosssection showing the tug link in position engaged in the fasteningdevice.

Referring now to the drawings, A designates the device as a wholeadapted to be rigidly secured to the hame H by projections a (at thelower end) and a (at the upper end) of the device,these being extendingthrough the hame and upset at their extremities as rivets.

The device A consists of a bar or staple a extended transversely at itsends by the terminal projections a a Between the two terminals, the bara is flanked by downwardly and outwardly inclined sides or Webs apierced by apertures a at regular intervals to admit the engaging hookor books of a tug link L, as in Fig. 5. The inclined sides mergerespectively in a rectangular base wall constituting a continuous loweredge of the structure, designed to rest at the bottom at all points uponthe face of the hame as in Figs. 2 and 5, being held thereto by theterminal extensions a a of the bar (4. Thus the bar a with its inclinedsides (0 connected across at the ends, forms an inverted trough-likestructure in which the sides constitute supporting and strengtheningwebs adding very greatly to the resisting power of the bar or staple (1against the side stresses of draft of the tug link L, while at the sametime the apertures a reduce the quantity and weight of metal employedwithout diminution of strength. The series of apertures is to enableadjustments of the tug link L upwardly or clownwardly as may berequired. This is done by turning the link over to a position oppositethat shown in Fig. 5, and pushing it out of connection with the bar aand reengaging it by the same manipulation reversed in the desired newrelation with the bar through the appropriate openings a In order toassist in holding the link against displacement when in position, Iemploy a yielding loose strip of sheet metal B, bent up to a V orinverted U cross section, laid upon the face of the hame within thehollow of the device A without fastening. It extends approximately fromend to end of the structure, and bears upwardly against the hook orhooks of the tug link L and is under slight compression when the tuglink is in place.

The construction, as will be seen, is exceedingly simple, light in aWeight, exceedingly strong in resisting power for its intended use, andis also economical in 00st a member comprising alongitudinally-extending bar and Webs diverging therefrom and connectedto each other at opposite ends, said member being rigid With pr0jectionsfor fastening the member to the hames, the divergent sides of saidmember being perforated in alinement for the reception and attachment ofa link in adjusted pcsitions, and a strip of resilient material "(ifsubstantially arched form in cross section adaptedto seat on the'hainesand to be confined ,in the housing formed between the inner Wallsof the divergent sides and; the closed ends of said member.

In testimony whereof I have hereunto set 5 nesses 7 JAMES M.' HUDSON.lVitnesses:
